Does your home have an underground heating oil tank? How can you find out?

The only way to know for sure if a tank is still buried is to have an oil tank search performed. That said, there are a few things you can on your own to see if a tank is even likely. This involves looking for evidence of a previous or existing tank, and looking for records related to oil tanks.

The first thing you want to think about is the age of the home. Homes build after 1980 will almost never have an oil tank. But any home might have a tank if it were built in the 70ss or before. This is also true if the neighborhood itself was already there prior to the 1970’s.

If you live in Oregon then you can check the Oregon DEQ’s records related to oil tank decommissioning. (Below) Washington doesn’t have a publicly searchable database of the like.

Next you can look around your property for any of the signs of a heating oil tank (Below), if you find any of these signs then it is likely there is an underground tank. remember though, finding nothing is not proof that there isn’t a tank.

The oil tank sweep involves a search through the above listed public records and may include searching though historic imagery and neighborhood trends. The on-site investigation searches for signs of oil oil plumbing (as seen in the signs of oil page) then uses a variety of metal detectors and magnetometers. We have some special tools that we can use when called for. These can help find what something is when there is a something.

What do we find? Metal cesspools, septic tanks, home gasoline tanks, second underground oil tanks, buried barbecue grills, and much more! We will investigate any large metallic underground objects and note them in the official letter of our findings.
